20-Ounce Wide Mouth Flex Sip Lid Flask

[This review was collected as part of a promotion.] I previously had the Hydfroflask Coffee mug with standard lid and expected the lid to leak, however I purchased this model because it was sold as leak proof. It is not leak proof and started leaking between the two sections of the Flex Sip lid after only a couple of uses. Coffee is only luke warm after 2-3 hours. Bummer . . .

[This review was collected as part of a promotion.] Replaced my coffee/water bottle under warranty and the new one is perfect. Thanks

The perfect little grab-and-go coffee mug for the car; I love it.

This is a faulty product being peddled by a company with no shame that is well aware of the blatant design flaw and continues to sell it anyway. They replaced the lid and thennew one has the same problem. It leaks with every sip. I've seen prank dribble cups do a better job of holding liquid.

Great size, amazing insulation. Durable. I thought the lid was going to be complex, but I love it. Zero issues sealing, after a crazy first year of use

This is my second one and I love it. Great color. Just wish the lid was a bit easier to clean. Will buy again for sure. Great that it has a handle to carry it.

Large enough that it’s enough tea for my entire morning yet stays warm. Can switch lids to suit your preference. My only regret in buying this is that I didn’t get it engraved!

[This review was collected as part of a promotion.] I was so sad when I lost my 4 year old hydroflask this summer! It was the only travel mug I'd ever found that didn't leak coffee, so I used it every day, for years. I bought two new hydroflasks, even though they had this new lid design. One of the two lids was fine at first but started leaking after 3 weeks. I have now switched to using the second lid only, but this week i noticed a small amount of coffee along the seams when I tilted it for use. i am so disappointed! My previous experience had been nothing but spectacular. Now I have two new expensive travel mugs as leaky as all the others I paid a lot less for.

[This review was collected as part of a promotion.] Great products but my lid is leaking. Was a gift from me so he just started using.

[This review was collected as part of a promotion.] This is my second one. I lost my first and so happy to have a new one now. Love it!!

The bottle itself is good. easy to sip from it with one hand. Perfect for morning coffee while reading news. The only problem: it has a "flex sip" lid on it, and the lid is impossible to clean. I have the same problem as in another review by Angela: black gunk builds up in the layers of the lid and occasionally falls out into the drink or clogs the siping hole. (I put milk in my coffee, and I think that adds to the gunk also). This is not a manufacturing error -- this is a serious design FLAW!
